The story takes place at the end of the 19th century, as Japanese culture gains popularity in the West. A young Japanese girl, Yune, accompanies a French traveler, Oscar Claudel, on his journey back to France, and offers to help at the family's ironwork shop in Paris. Oscar's grandson and shop owner Claude reluctantly accepts to take care of Yune, and we learn how those two, who have so little in common, get to understand each other and live together in Paris in the 1800s.
